Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, in particular to a glue gun with adjustable spacing. Background Art

[0002] A glue gun is a tool used to extrude adhesives such as hot melt glue and glass glue. When the electric glue gun is powered on, the motor inside it starts to run, and the motor drives the extrusion device forward through the transmission mechanism. There is a heating element inside the glue gun, which heats the glue tank of the glue gun. The heating element heats the glue stick and gradually melts it into liquid glue. As the extrusion device advances, pressure is applied to the melted glue, forcing the glue to be squeezed out of the glue nozzle. The speed and amount of glue output can be adjusted by controlling the motor speed and running time.

[0003] However, existing glue guns are usually equipped with multiple glue nozzles for dispensing glue to complete the gluing operation of a large area or a large number of parts. These glue nozzles are usually fixedly connected to the glue gun, and the spacing of the glue dispensing cannot be adjusted, thereby failing to meet the use requirements of dispensing glue at different spacings.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-Figure 3 The utility model provides a technical solution: a glue gun with adjustable spacing, comprising a glue gun body 1, a connecting seat 2 is arranged on one side of the glue gun body 1, a bolt 3 is connected inside the connecting seat 2, an air guide port 4 and a glue guide port 5 are arranged inside the connecting seat 2, a glue nozzle 6 is connected to one side of the connecting seat 2, the glue nozzle 6 is connected to the air guide port 4 and the glue guide port 5, the connection mode between the connecting seat 2 and the glue gun body 1 is a sliding connection, and the connection mode between the connecting seat 2 and the glue nozzle 6 is a fixed connection;

[0034] It is worth mentioning that: the connecting seat 2 is stably connected to the glue gun body 1 by the bolt 3. When the distance between the glue nozzles 6 needs to be adjusted, first loosen the bolt 3 to release the stable connection between the connecting seat 2 and the glue gun body 1, then push the connecting seat 2 and drive the glue nozzle 6 to slide on one side of the glue gun body 1. When the distance between the glue nozzles 6 is adjusted to an appropriate length, stop pushing the connecting seat 2, and then stably connect the connecting seat 2 to the glue gun body 1 by the bolt 3.

[0035] See also Figure 1-Figure 5 A fixed block 7 is fixedly connected to one side of the glue nozzle 6, a slider 13 is provided on one side of the fixed block 7, a locking assembly is provided inside the fixed block 7, and the locking assembly is used to lock the fixed block 7 and the slider 13. A cylinder 20 is provided on one side of the glue gun body 1, and the cylinder 20 is connected to a driving assembly.

[0036] It is worth mentioning that after the fixing block 7 and the slider 13 are locked by the locking assembly, the driving assembly can drive multiple nozzles 6 to move simultaneously, thereby adjusting the distance between the multiple nozzles 6 at the same time, which is conducive to improving the convenience and efficiency of operation.

[0037] See also Figure 1-Figure 7 The locking assembly includes a reset spring 8 and a card block 9. The card block 9 forms a telescopic structure inside the fixed block 7 through the reset spring 8. The outer surface of the card block 9 is sleeved with a collar 10. The connection between the collar 10 and the card block 9 is a rotational connection. The outer surface of the collar 10 is fixedly connected with a shift block 11. The outer surface of the fixed block 7 is provided with a slide groove 12. The inner part of the slider 13 is provided with a card groove 14. The connection between the card block 9 and the card groove 14 is a snap-fit ​​connection.

[0038] The principle of locking and unlocking the fixed block 7 and the slider 13 is as follows: when the fixed block 7 and the slider 13 need to be locked, the shift block 11 is first rotated so that the shift block 11 drives the collar 10 to rotate on the outer surface of the clamping block 9. When the collar 10 rotates 90°, the rotation of the shift block 11 is stopped. At this time, the return spring 8 pushes the clamping block 9 to extend out from the inside of the fixed block 7, and the clamping block 9 is engaged with the clamping groove 14. The clamping connection between the clamping block 9 and the clamping groove 14 can connect the slider 13 and the fixed block 7 to each other, thereby locking the fixed block 7 and the slider 13. Interlocking, when it is necessary to release the lock between the fixed block 7 and the slider 13, first pull the shift block 11, and the shift block 11 drives the card block 9 to move synchronously through the ring 10, so that the card block 9 slides into the interior of the fixed block 7 and separates from the card slot 14, and the reset spring 8 is squeezed and compressed. When the card block 9 slides to the innermost part of the fixed block 7, the shift block 11 is rotated 90° in the opposite direction. At this time, the slide slot 12 can limit the shift block 11, so that the card block 9 is stabilized inside the fixed block 7, and the lock between the fixed block 7 and the slider 13 is released.

[0039] See also Figure 1-Figure 6 The driving assembly includes a limit plate 15, a limit groove 16 is provided inside the limit plate 15, the limit groove 16 is inclined, a slider 13 is provided inside the limit groove 16, a support plate 19 is fixedly connected to one side of the limit plate 15, a guide rail 18 is connected to one side of the support plate 19, and the guide rail 18 is fixedly connected to the glue gun body 1.

[0040] The principle of batch operation of multiple glue nozzles 6 is: first, for the glue nozzles 6 that need to be position adjusted, the fixed blocks 7 connected to these glue nozzles 6 are locked with the corresponding sliders 13 through the locking assembly, and then the cylinder 20 is controlled to work, the cylinder 20 drives the limit plate 15 to rise and fall, the limit plate 15 drives the slider 13 to move, and the limit groove 16 will limit the movement of the slider 13, so that the slider 13 moves horizontally, and the slider 13 drives the glue nozzles 6 to move synchronously through the fixed block 7, so that the distance between the multiple glue nozzles 6 can be adjusted at the same time.

[0041] See also Figure 6 The two ends of the limiting groove 16 are fixedly connected with baffles 17 , the inner diameter of the baffle 17 is smaller than the outer diameter of the slider 13 , and the inner diameter of the baffle 17 is larger than the diameter of the block 9 .

[0042] The baffle 17 has the function that the block 9 can pass through the baffle 17 to be connected with the slider 13 , and the baffle 17 can limit the slider 13 to prevent the slider 13 from falling off from the limiting groove 16 .
